So you'll actually jump to the absolute *machine* address? That way
you'll need to patch them up at load time. If they were relative to the
start of the code, you could just save them and get reloadable bytecode,
without a need for patching up anything at all.
Oh well. There are pro's and cons to everything. I just get the feeling
that your choice as displayed here, originates in conservatism, i.e. do
the same as physical CPU's do. There's no need for that restriction.
This isn't a real CPU.
